Adding configuration to allow safety comment above stmt containing unsafe block
Adding a new configuration, `accept-comment-above-statement`, to allow a safety comment to be placed before the statement that has the `unsafe` block. It affects the `undocumented_unsafe_blocks` lint.
The default value for this configuration will be `false`. So the user has to opt-in for the change.

Ignore more type aliases in `unnecessary_cast`
This is potentially the worst code I've ever written, and even if not, it's very close to being on par with starb. This will ignore `call() as i32` and `local_obtained_from_call as i32` now.
This should fix every reasonable way to reproduce #10555, but likely not entirely.

new lint: `drain_collect`
Closes#10818.
This adds a new lint that looks for `.drain(..).collect()` and suggests replacing it with `mem::take`.

[`match_same_arms`]: don't lint if `non_exhaustive_omitted_patterns`
Fixes#10327

from_over_into: Show suggestions for non-Self expanded paths
changelog: [`from_over_into`]: Show suggestions when the body contains macros not expanding to `Self`
Currently any path in a macro expansion causes the suggestion to be hidden, meaning most macro calls cause it to be hidden
Now it's only hidden if the expansion contains `Self`
[`unnecessary_fold`]: suggest turbofish if necessary
Fixes#10000
This adds turbofish `::<T>` to the suggestion in `unnecessary_fold`. This is necessary because the `Sum` trait is generic, which breaks inference when changing `fold()` to `sum()`.

new lint [`single_range_in_vec_init`]
Lints on `vec![0..200]` (or `[0..200]`), suggesting either `(0..200).collect::<Vec<i32>>()` or `[0; 200]`.
Haven't tested it with anything that isn't primitive. Probably should!

[`derivable_impls`]: don't lint if `default()` call expr unsize-coerces to trait object
Fixes#10158.
This fixes a FP where the derive-generated Default impl would have different behavior because of unsize coercion from `Box<T>` to `Box<dyn Trait>`:
```rs
struct S {
x: Box<dyn std::fmt::Debug>
}
impl Default for S {
fn default() -> Self {
Self {
x: Box::<()>::default()
// ^~ Box<()> coerces to Box<dyn Debug>
// #[derive(Default)] would call Box::<dyn Debug>::default()
}
}
}
```
(this intentionally only looks for trait objects `dyn` specifically, and not any unsize coercion, e.g. `&[i32; 5]` to `&[i32]`, because that breaks existing tests and isn't actually problematic, as far as I can tell)
